Getting errors
Things seemed to go well when I executed the JavaGuard to obfuscate a jar file I had, but then I got this. I am sure, it's something wrong I am doing. Please help!

JavaGuard v1.0beta4 Bytecode Obfuscator
Building the file containers...
Building the class tree...
Generating the mapping table for the whole class tree...

Unrecoverable error during obfuscation:

Sorry, I haven't seen your post earlier...

The reason why I begun working on that is that the company I'm working for doesn't offer the sources of their products. We've been using RetroGuard to protect our code, but it lacked some features we urgently needed so I implemented them.

RetroGuard is an open-source software tool so we have to give the changed sources back to the public so that everyone can profit :-)

It is interesting that a tool to actually reduce the liberty of the users as this one is under the GPL... Maybe the Author wants to improve Open Source, helping to avoid reversing... :)
